Goals from Loren Moron and Joaquin gave Real Betis a first-leg advantage over Valencia but Denis Cheryshev and Kevin Gameiro struck back.
Kevin Gameiro inspired a late comeback as Valencia battled to a 2-2 draw in their Copa del Rey semi-final first leg at Real Betis.
Loren Moron put Betis ahead on the stroke of half-time and Valencia were left with a tall task when goalkeeper Jaume Domenech allowed veteran winger Joaquin to score direct from a corner.
Head coach Marcelino responded by sending on Gameiro and the French striker crossed for Denis Cheryshev to head Los Che back into the tie.
